AWS Security group Critical alerts

How do we change the critical alerts for AWS security group changes to OK ?

We have done a known update to the security groups for a EC2 instance. Check_mk notifies it as a critical alert. How do we acknowledge and convert it OK as it is a known update.

Have you tried to re-run a discovery? Maybe you can set it to undecided in WATO and the re-run will it discover as ok after this.
